Advances in eutrophication science within Lake of the Woods, a complex transboundary lake – Forward to the special section

Outside of the five Great Lakes, Lake of the Woods (LoW) is the largest transboundary lake shared by Canada and the United States. Over the last two decades, an international consortium of researchers has advanced our understanding of eutrophication science in this complex watershed. This introductory paper outlines eleven research articles included in this special section, within three main themes pertinent to LoW: external phosphorus sources to LoW and internal phosphorus loading, lake and watershed modeling, and new insights into cyanobacterial and harmful algal blooms (cHABs). We conclude with a roadmap to guide future transboundary water quality management in LoW, including remaining research gaps and future monitoring needs.
